Vegetables and Anti Cancer-(part 2)
How it combats cancer: This nutrient-dense food contains many anticancer properties. It’s loaded with beta-carotene, which may protect DNA in the cell nucleus from cancer-causing chemicals outside the nuclear membrane.
Diet tips: Go for freshness when picking potatoes - canned arieties contain less beta-carotene and vitamins C and B. Naturally sweet and creamy, mashed sweet potatoes can be enhanced with a little apple juice. Or whip the cooked tubers with orange zest or orange juice and season with cinnamon,nutmeg, and ginger.
How it combats cancer: Grapefruits, like oranges and other citrus fruits,contain monoterpenes, believed to help prevent cancer by sweeping carcinogens out of the body. Some studies show that grapefruit can inhibit the proliferation of breast-cancer cells in vitro. It also contains vitamin C, beta-carotene, and folic acid.
Diet tips: Grapefruit can be sweetened with brown sugar or a drizzle of maple syrup or honey; vanilla extract, fresh mint, and almonds also accent the fruit’s flavor. Grapefruit juice will give you the antioxidants and phytochemicals that fight cancer, but it’s missing the fiber that fresh,whole grapefruit offers.
How it combats cancer: Avocados are rich in glutathione, a powerful antioxidant that attacks free radicals in the body by blocking intestinal absorption of certain fats. Ounce for ounce, avocados also supply 60 percent more potassium than bananas and are a strong source of beta-carotene.
Diet tips: Store avocados at room temperature until they soften. If you don’t eat the fruit immediately after cutting, sprinkle on some lemon or lime juice to keep it from darkening. Add chunks or slices to salads and sandwiches or spread mashed avocado on bread.
How they combat cancer: Seaweed and other sea vegetables contain beta-carotene, protein, vitamin B12, fiber, and chlorophyll, as well as chlorophylones - important fatty acids that may help in the fight against breast cancer. Also, many sea vegetables have high concentrations of the minerals potassium, calcium, magnesium, iron, and iodine.
Diet tips: Sea vegetables come fresh, dried, or powdered. Both the Japanese & the Irish regularly use them as flavorings for broths & soups,stir-fried over rice, or as a wrap for fish and other seafood. Varieties such as dulce, wakame, kombu, and hijiki even appear in pancakes,salads,puddings, and sandwiches.
How it combats cancer: Soy contains several types of phytoestrogens -weak, nonsteroidal estrogens that could help prevent both breast and prostate cancer by blocking and suppressing cancerous changes. Genistein,one type of phytoestrogen, also lowers breast-cancer risk by inhibiting the growth of epithelial cells & new blood vessels that tumors require to flourish.
Diet tips: Tofu is made by coagulating the protein in soybeans - much the way cheese is produced. While bland on its own, tofu absorbs other flavors when cooked, making it perfect for stir-fries, dips, spreads,shakes, even cheesecake. It’s also a good high-protein substitute for meat, whole milk & mayonnaise.
